Answer / meenakshi

am not getting ur question properly. but still, i wanna
mention one thing that i kno. Basically, there are two
kinds of mccb...conventional and current limiting...in
current limiting, there will be two contacts, lower contact
n upper contact which vil be in the form of strip.current
in lower n upper contact are opposite in direction. when a
heavy fault current flows, there vil b more repulsive
force.thus the contcts comes apart.this is one part in
working of that mccb.but am not sure whether this the
answer what u r expecting.
